Unbound control question

(0) ShareShare
ReportReport
Posted on by Kevin Murray 1,005

I'm new to X++, and I want to put an unbound
checkbox on a tab in the sales header form
(SalesTable).  When the configure line button is
pressed on the bottom half of the form for a sales
line, I need to have code in that other class
check the on/off status of the unbound control in
the SalesTable form and do something.  I really
don't need the database to record the status.

The current status is I've placed the checkbox on
the form, see it on the diaply and can click it,
but can't refer to it.

My question is how do I refer to the unbound
control in the SalesTable form from another class
and, is this the right approach?

    You can do it via a display method on form.

    The flow is...the user will click a checkbox on SalesTable when they want the functionality to work, unmark when they don't. They will then press the configure button on the lower SalesOrder screen which will invoke Product Builder. The button code has been modified to include a class that will copy the sales line (or won't if the checkbox hasn't been marked), so there really isn't a form, just a class. In the class I want code to go (psuedocode: if flag checked then continue, otherwise return). This is all AX 2009 but probably the same regardless.

    Unless I'm totally misunderstanding.

    1. Declare Map/List variable in classDelaration and create object in forms init method like:

    Map   salesTableMap;

    salesTableMap = new Map(Types::String, Types::Record); // please use list instead of MAP

    2. Create edit method on SalesTable datasource:

    edit NoYesId markUnboundedChkBox(boolean _set, SalesTable _salesTable, NoYesId _value)

     {;

     if(_set)

     {

         if(_value)

            salesTableMap.insert(_salesTable.SalesId, _salesTable);

         else

            salesTableMap.remove(_salesTable.SalesId);

         }

         return(salesTableMap.exists(_salesTable.SalesId));

     }

    3. drop this edit method on form.

    4. Write following code on button:

    void clicked()

    {

        super();

        if (salesTableMap.exists(salesTable.SalesId))

        info("Enable");

        else

        info("Disable");

    }

    [quote user="Kevin Murray"]The flow is...the user will click a checkbox on SalesTable when they want the functionality to work, unmark when they don't.[/quote]This is not the way in which the standard application works. In the standard application a user must select records on a grid he/she needs to be processed (using Shift or Ctrl to mark multiple records) and then just press an appropriate button on a form. The menu item for the button must have MultiSelect set to Yes. A class that is called via the menu item should collect all the selected records from the datasource and then process them on the server side. To grab all the selected records you can use FormLetter::getFormRecord() - it return a packed map (RecId -> Record buffer) with the selected records; in your class you can unpack the map on the server side and process them one by one. This perfectly works regardless of the number of records selected, i.e. even if a user selects just one single record, and you don't have to modify every form to to be able to process multiple records at once.

    As to implenemting an edit method backed by a Map or something, consider this:

    • If a users marks some records and then applies a query filter that narrows the resultset (but marked records are still in the resultset and thus can be visible on a form), what are you going to do with the marks stored in a collection class? Will you just clear all the marks, or keep them, or try to keep only marks for records in the resultset?
    • If a user removes a filter applied earlier, will he/she be able to see marks that were set before applying the filter?
    • If you deside to keep marks only for those records in the current resultset (i.e somehow remove marks for those record that a user cannot see on the form with the current query filters applied) then how are you going to achieve that? How will it impact performance, client-server traffic and overall workload?
